Background and aims Minirhizotrons are commonly used to study root turnover which is essential for understanding ecosystem carbon and nutrient cycling. Yet, extracting data from minirhizotron images requires extensive annotation effort. Existing annotation tools often lack flexibility and provide only a subset of the required functionality. To facilitate efficient root annotation in minirhizotrons,...
Background and Aims Roots express morphological and physiological plasticity that may be adaptations for efficient nutrient capture when soil nutrients are heterogeneous in space and time. In terms of nutrient capture per unit of carbon invested in roots, morphological plasticity should be more advantageous when nutrient patches are stable in time, and physiological plasticity when nutrients are variable...
